Prompting · How Founders Use AI

How do I give AI the right context about my business (projects, custom instructions, memory)?

Stop re-explaining your company in every chat: write a one-page brief (what you sell, who your customers are, your tone, your goals) and put it where the AI can always see it. In ChatGPT that means custom instructions plus a Project with your key docs, and a Project can now also take Google Drive folders and Slack channels as sources. In Claude, a Project with its knowledge base works the same way, and each project keeps its own memory. Memory picks up preferences over time. Once the context lives in the tool instead of in your prompts, every answer starts from 'knows my business' instead of 'generic advice'.
